Body Mass Index (BMI)

BMI is one of the most common ways to assess your health based on your weight and height. It classifies you as underweight, normal weight, overweight, or obese. You can estimate your BMI by dividing your weight in kg by your height in meters squared or using a BMI Calculator. The following table highlights the BMI range as per the World Health Organization (WHO):

BMI Range

Waist-to-Height Ratio

The Waist-to-Height Ratio (WHtR) measures the body fat distribution by assessing your waist or abdominal fat and height. It is calculated by dividing the waist circumference (in cm) by the height (in cm). The ratio is used to flag chronic diseases, such as type 2 diabetes and cardiovascular diseases. A WHtR below 0.5 is considered healthy for both men and women. You can use the following chart to calculate your ideal weight based on the waist-to-height ratio:
